CARBURETER.

SPECIFICATION forming part of LettersrPatentNo. 706,454, dated August 5, 1902.

Application filed January 27, 1902. Serial No. 91,436. ,iN-o modeli) i .To all whom t may concern.:

Beit known that I, CLARK RoBINsoma citizen of the United States, residing at Hart-v ley, in the county of OBrien and State of Iowa, have invented certain new and useful theart to which it appertains to make the same.

This invention relates to certain novel and useful Improvements in` carbureting apparatus for the manufacture .of illuminatinggas of the kind obtained by charging and mirring air under pressure with the vapor `of a hydrocarbon liquid.

in construction, positive in operation, which shall produce an intimate `mixture ofthe at-c mospheric air and the hydrocarbon vapor,

and is capable of su pplying an illuminating-` gas of any desired richness. I

carbureter, means producing` an intimate commingling of the same therein to obtain a gas of any desired richness,'and` means for conducting the gas from the carbureter to the points of use.` c c c ,l

Specifically stated, it consists ofautomatically-operated mechanism under the impulse of water-pressure for supplying air as needed to a carburetor, (the construction of which carburetor will be hereinafter more fully described,) a reservoir for supplying the hydrocarbon liquid to the carbureter, means in said carbureter for mixing the air and hydrocarbon vapor, straining, refining, and diluting the resultant gas to any desired quality, and means for conducting the gas from the carburetor to the burner or the point of use.

For afull understanding of the merits and advantages of the invention reference is to be had to the accompanying drawings and the followingl description.

The invention is susceptible to various changes in the form, proportion, and minor details of construction without departing from the principle or sacrificing any of the ofthe framework 1.

A: by means of the U -shaped pipes 1415.

advantages thereof, and a disclosure of the invention and adaptation thereof is shown in theaccompanying drawings, in which- Figure 1 is a side elevation of an apparatus embodying my improvements. Fig. 2 is a detail vertical sectional view of the carbureter-tank or carburetor proper, showing the `interior` construction thereof.

In referring.V to the drawings in detail like numerals; designate like parts.

The air forcing oI-.blowing mechanism I have designated as a whole by A, as will be It consists Mounted on the floor of the framework are bell-tanks or wateI--seal seen by examining the drawings.

.tanks 2 3` for pumping air into thek storagec c I 'f Vtank 4. This is accomplished by connecting The object of my Invention, is to provide a' carbureting apparatus which shall besimple `the inverted or bell portions 5 and 6 of the ,tanks12and 3 with the chain,rope, or similar means 7, which extends up over the sprocketwheel 8, which is oscillated by means of the rrack 9, the rack in turn having a reciprocating movement imparted thereto by the uid- Y l l operatedpiston mechanism 10, water being Broadly and generically speaking, the in-y vention consists in means for supplying at-, mospheric air and ahydrocarbon liquid to the'l lsupplied under pressure to said mechanism by any suitable means, such as pipe 11. Air is introduced into the pumpingtanks by means of pipes 12 13, extending through the bottom of the same. The pumping-tanks are in turn each connected with the storage-tank A The operationlof this partof `the y apparatus will thus be apparent. Fluid-pressure being ad- `mittedtothe piston mechanism lO for actuating the same the rack 9 will be reciprocated, thus oscillating the sprocket S, this causing the inverted-bell portions 5 and 6 to be alternately raised and lowered, thus forcing the air which has `been admitted through pipes l2 and 13 to the storage-tank 4. When sufficient air has been stored in tank 4, fiuidpower is cut off from the engine 10 by the valve 16, which is operated by the chain 17 and weight 18, secured to the inverted portion of the storage-tank. As the latter nils with air the bell portion is forced upward, this operating to pull the chain and close the valve, and as the belltank descends and empties the valve is opened.

Air is conveyed from the storage-tank 4: by means of pipe 18' to the carburetor, which I shall designate asa whole by B. The latter consists of the chamber 19, containing the tanks 20 21. For illustrative purposes I have shown but two tanks, but as many as desired may be employed without departing from the invention. The air-duct 18' passes through cally-arranged pipes 22, which are open and terminate some distance above the bottom of the tank 20. Hydrocarbon liquid is supplied from the reservoir C to the chamber 19 through the pipe 23, the supply being controlled by suitable means, preferably the float-valve 24. Oil being admitted to chamber 19 passes through the apertures or ports, as 25, into the tanks 20 and 2l, the same level ot' liquid being always maintained in the tanks 20 and 2l and chamber 19. Air on being conducted from the storage-tank through the pipe 18 enters the cone-like chamber 21 and from there passes through pipes 22 into the hydrocarbon liquid in the chamber 20. Carrying with it the hydrocarbon vapor, it lters or passes up through a body of suitable material 24:, (preferably excelsior,) which acts as a condenser, then passes through a series of strainer-plates, as 25. These plates are com- Vposed of a series of thin perforated sheets of metal,.preferably tin, and have a layer of suitable absorbent material,preferably cotton, interposed between the same. The gas passes through thepipe 26 to the chamber 2l,-where the same operation is repeated, the gaseous mixture passing from funnel-like chamber through vertical pipes to the oil, then through condensing material to and through the strainer-plates to top of chamber. From there it is conducted, as shown, to the strainer 27, where itis again refined. This strainer is composed of a series of perforated metal plates 28,with interposed layers of cotton, similar to the straining-plates of the tanks 20 2l. From this strainer the gas -is conducted by suitable means, as pipe 29, to

p the place of consumption. If the gas is too rich, it may be diluted in the strainer 27 by means of air, which is conveyed thereto by a pipe, as 30, which is connected with pipe 18, as shown. A valve 3l controls the admission of the air from pipe 18 to pipe 30.

y.As the operation of my apparatus will be perfectly apparent from the above descripvtion when read in connection with the accompanying drawings, it is unnecessary to further describe the same.
